You can't. The consequences of failing courses in college are still very serious. First of all, you will be disqualified from the awards this semester. Secondly, it will be recorded in the file. If you fail in the college entrance examination, even if it is a postgraduate entrance examination, the teacher will see it. There are so many people who failed in the exam. How can you compete with others if you fail the exam? It is obviously unrealistic. But if your grades are good enough, the postgraduate entrance examination will not affect you. Of course there are exceptions. If you publish papers in professional journals or have any scientific and technological works, you are likely to continue to be insured for research. So come on! Don't be abandoned because you failed the exam, and don't be entangled in research that can protect yourself.
